Abstract
An alkaline battery comprises an electrode. The electrode has a current collector and an active substance filled in the current collector. The current collector includes a nonwoven fabric fabricated from a plurality of fibers and a nickel-plating film formed on the plurality of fibers. A specific surface area per unit volume of the current collector is 0.13 m2/cm3-0.35 m2/cm3.
